Medicinal and Aromatic Crops Technologies Developed/Varieties Released

Microtuber production protocol in Gloriosa superba was standaridsed. The micro tubers evolved were advanced for three generations until the tubers bulked to 40-45 g weight which is the acceptable form to farmers. This technique is useful for generation of quality planting material (tubers) on sustained basis, saving in the cost of tubers upto Rs.1.0 lakh per acre and uniformity in crop growth leading to higher seed yield when compared to the conventional practice .
